Question 1:¶

Recreate the barplot below that shows the population of different continents for the year 2007.

Hints:

  • Extract the 2007 year data from the dataframe. You have to process the data accordingly
  • use plotly bar
  • Add different colors for different continents
  • Sort the order of the continent for the visualisation. Use axis layout setting
  • Add text to each bar that represents the population
In [3]:
seven = df[df["year"]==2007]
sev =seven.groupby(seven["continent"]).sum()
ves= sev.reset_index()
fig = px.bar(ves,y="continent", x="pop",color="continent")
fig.update
fig.show()

Question 2:¶

Sort the order of the continent for the visualisation

Hint: Use axis layout setting

In [4]:
fig = px.bar(ves,y="continent", x="pop",color="continent")
fig.update_yaxes(categoryorder="total ascending")
fig.update_layout(showlegend=False)
fig.show()

Question 3:¶

Add text to each bar that represents the population

In [5]:
fig = px.bar(ves,y="continent", x="pop",color="continent", text="pop", text_auto=".2s")
fig.update_traces(textposition="outside", cliponaxis=False)
fig.update_yaxes(categoryorder="total ascending")
fig.update_layout(showlegend=False)
fig.show()

Question 4:¶

Thus far we looked at data from one year (2007). Lets create an animation to see the population growth of the continents through the years

In [6]:
fd =df.groupby([df["continent"],df["year"]]).sum()
ddf= fd.reset_index()
fig = px.bar(ddf,y="continent", x="pop",animation_frame="year",animation_group="continent",color="continent", range_x=[0,4000000000])
fig.update_yaxes(categoryorder="total ascending")
fig.update_layout(showlegend=False)

fig.show()

Question 5:¶

Instead of the continents, lets look at individual countries. Create an animation that shows the population growth of the countries through the years

In [7]:
fig = px.bar(df,y="country", x="pop",animation_frame="year",animation_group="country",color="country", range_x=[0,1400000000])
fig.update_yaxes(categoryorder="total ascending")
fig.update_layout(showlegend=False)
fig.show()

Question 6:¶

Clean up the country animation. Set the height size of the figure to 1000 to have a better view of the animation

In [8]:
fig = px.bar(df,y="country", x="pop",animation_frame="year",animation_group="country",color="country", range_x=[0,1400000000], height=1000)
fig.update_yaxes(categoryorder="total ascending")
fig.update_layout(showlegend=False)
fig.show()

Question 7:¶

Show only the top 10 countries in the animation

Hint: Use the axis limit to set this.

In [9]:
fig = px.bar(df,y="country", x="pop",animation_frame="year",animation_group="country",color="country",range_y=[131.5,141.5], range_x=[0,1400000000])
fig.update_yaxes(categoryorder="total ascending")
fig.update_layout(showlegend=False)
fig.show()
